Abstract
A device mounted about a tool handling spindle of a machine tool for entrapping dust and particles produced in the milling of a graphite workpiece. The device uses Electric Discharge Machining (EDM) fluid to form a closed envelope surrounding the milling point. The device includes a collar having a first annular groove in fluid communication with an endless radial nozzle which emits the fluid envelope. The collar also includes a second annular groove concentrically disposed in relation to the first annular groove. An adjustable spraying attachment for use in directing a flow of EDM fluid on or about the milling point, is attached to the collar and in fluid communication with the second annular groove.
